A neural interface is a device that is used to connect the brain to a computer. It is typically implanted into the brain, and consists of a series of electrodes that are used to record the electrical activity of the brain. The data from the electrodes is then transmitted to a computer, which is used to interpret the data and provide feedback to the user.
Some of the emerging trends in neural interfaces include the development of wireless devices, the use of nanomaterials to improve device performance, and the use of flexible and biocompatible materials to reduce implantation risks.
